Currently, I faced the issue of getting NORMAL_TEMPORARY_FAILURE when FreeSWITCH is originating outbound calls to the PSTN via Dinstar GSM gateway device.

I follow the guides from FreeSWITCH confluence and the inbound call is working fine. 

My Dinstar Gateway device version is UC2000-VE Business.

Any help would be appreciated.

Best regards,
